For exponential functions
y=ab^x,
where
a is the scale vertical stretch factor,
b is the base, and
x the exponent (also independent variable)
It is a know fact that if the scale factor (1/2 or 2 in the answer choices) is positive, the graph is increasing if the base (3 or 1/3) is greater than 1.
This means that the base cannot be equal to 1/3. This eliminates choices 3 and 4.
Next, for a base greater than 1 (3>1), and the scale factor positive, it is a dilation (image gets bigger) if the scale factor is greater than 1. This eliminates the first choice where a=2.
This leaves us with the second choice where a=1/2, b=3, which is a shrink of the given exponential base function.
Answer:
1.75 cases need to be sold
Step-by-step explanation:
The complete question is
The high school tennis team is selling tennis balls to raise $500 for new equipment.They sell the balls for $2 each.
4).How many cases of tennis balls does the tennis team have to sell in order to raise enough money for new equipment.
Solution
Price of each ball = $4
No. of balls in each package = 3
Total number of balls that need to sold in order to raise $500 is
one package = 3balls
Hence no of packages to be sold
packages and 2 balls or total 42 packages
1 case has 24 packages , thus total number of cases to be sold = 
Answer:
y = 27.1
Step-by-step explanation:
We have the value of x:
x = 12
and we need to find the value of y in the expression:
y = x + 15.1
as we can see by the equation, the value of y depends on the value of x.
thus, we substitute x = 12 on the previous equation:
y = 12 + 15.1
y = 27.1
the value of y is 27.1
Answer:3
Step-by-step explanation: 3(3)-4 =5
Area now is 5•5 equivalent to 25 :)
